Abstract: The invention relates to a head-up display system comprising: a processing module (1) designed to determine modified data representing a deformed image according to initial data representing an original image and deformation data defining an image deformation; a device (2) for generating a light beam representing the deformed image; and a projection device (3) designed to project the light beam in an adjustable direction towards a semi-transparent panel (4). The processing module (1) is designed to select the deformation data from a deformation table according to the adjustable direction.
